How to choose this product

handheld-ph-meter

A portable pH meter is a compact instrument for measuring the acidity or alkalinity of a liquid. It is small, light and often weatherproof, but has limited functions.

Applications

These instruments are for fieldwork use involving hydroponics, swimming pools and hot tubs, aquaculture, environmental and educational work, as well as waste, rain or drinking water purification.

Technologies

Using a meter is the most accurate way to determine pH. It is essentially a very sensitive volt meter whose probe generates an electric current when immersed in a liquid. The current varies with the concentration of hydrogen ions. Battery power makes these models portable.

How to choose

Choice will depend on intended use and the range of values to be measured.

Advantages

- Small size
- Light weight
- Practicality

Disadvantages

- Relative lack of precision
